9 Claims. (ECH.- 296-44) lo lng the window slightly open' and inserting a suitable instrument, such as a wire with a loop or hook on the end, through the opening to engage the regulator handle and turn the handle to swing the panel further open. This permits acl5 cess to the inside door latch handle which is operated to retract the latch bolt and thus open the door.

It is an object ci this invention to produce a thief-proof lock for this type of swinging window 2@ and which, among other things, will thwart entry into an automobile by theabove-mentioned manner.

ln the drawings: l Fig. lis a fragmentary7 side elevation of a venti- 2% lating window assembly in which the swinging window and regulator are provided with a lock 'which is the subject matter of this invention.

Fig. 2 is an assembly view showing the lock and swinging panel. 3@ 3 is a detail of the lock and swinging window panel regulator.

Fig. i is a vertical section through the window and door showing the window in locked position. Fig. 5 is a detail of the support plate for the `window glass lock.

Figs. 6, 7 and 8 are details of the window glass locking mechanism,

In the drawings the locking device is shown applied to the swinging panel l of the well-known Fisher no draft Ventilating window used on General Motors cars. In this type of window assembly: for example, the window opening t of the iront vehicle door t is arranged to be closed 5 by the front swinging panel l and the rear panel t which slides up and down, out -of-andfinto the window well in the well-known manner. The front swinging panel il is pivoted as at 5 and t to swing about a vertical axis between itsiront 520 and rear vertical edges.

'li'he lower pivot t takes the form of a shaft which is coupled to a worm gear 'l mounted vin the window regulator housing t. The gear 'l is meshed with, and driven by, a worm t carried on the spindle it. A suitable regulator handle l l is xed on the inner end of the spindle it. By

turning the handle ll,v which acts through the spindle It, worm t, gear 'l and shaft t, the window panel l may be swung to open or closed position.

The pitch of theworm 9 and worm gear l is il such that the action is self-locking or irreversible, that is, the worm 9 and handle ll cannot -be driven by force applied to the swinging panell. However, there is a small amount of play between the worm 9 and the gear l. This sometimes may lll permit the panel l to be pried open a slight distance. Then, too, the panel l projects a sum-y cient distance in back oi the pivots 5 and t that there is sucient spring in the glass panel l and the metal channel frame l2 in which the panel l l5 is mounted to permit the panel to be sprung slightly open when pressure vis applied by means of a suitable instrument to the channel l2 adjacent the rear vertical edge ofthe panel. While the window panel is pried open a slight distance, 20 a wire with a loop or hook,4V on the end-can be vinserted and the regulatorrhandle ll vturned to swing the panel further' open a sulilcient distance to obtain access to the interior of the vehicle body.

To prevent this and other possible ways of ob- 25 taining access to the interior of the car through the swinging panel, it is proposed to lock both the swinging panel and its operating regulator in closed position. Prefereably both the lockforthe regulator and the swinging window panel are 30 coincidentally operated through a single handle.

, For locking the swinging panel l there is provided a bolt it which is vertically reciprocable i in the bolt easing it. The casing It is supported by plate l5 which is secured by the screws it to 35 the belt rail Il in the window well. The bolt it is provided with an opening lil for the stud la. The stud I9 is n xed to the bolt it. such as by upsetting the end oi the stud l@ in the open- 'Ving it. The stud l@ passes through an elongated 40 opening 2t in the bolt casing it which permits the stud It to travel back and forth with the bolt Ilt.\

A latch operating lever handle 2l is pivotally mounted on the bolt casing ld by the pivot pin 22. The lever handle tl is provided with a cam opening 23 through which the stud l@ passes and in which .it engages the lever handle tl. A coil spring 2t Lis mounted over the stud it between the lever handle 2| in either locking or unlocking position.

It will be noted that, as viewed in Figs. 2 and 8, the lower end 26 of the cam slot 23 is closer to the center of rotation, namely, the pin 22 about which the lever swings, than the upper end, 21 ot the slot 23. Thus, when the panel I is in closed position and the lever handle 2| is swung counterclockwise the cam slot 23, acting through the ,stud I9, retracts the latch bolt I3 from the bolt opening 21 in the channel I2 and when the handle is swung clockwise from the dotted line position, the bolt I3 is projected upwardly into engagement with the opening 21 in the channel I2.

The garnish molding 28 is provided with a slot wear plate 3| provided with an outwardly pressed rib 32 is riveted or otherwise fixed to the top of the support plate I5. This wear plate 3| is positiori'd between the rubber weatherstrip 33 for the swinging window panel I and the lever handle 2|. The rib 32 is slidably engaged by the inside fece o! the lever handle 2| and guides the same when swung about its pivot 22.

For locking the window regulator a toothed gear or ratchet 34 is fixed upon the spindle I0 within the regulator gear housing 8. An opening 35 is provided in the side wall of the housing 8. A locking pawl 36, provided with an enlarged head 31, is supported in the opening- 38 in the lug 4I at the bottom of the lever 2|. The other end of the pawl 36 projects through the open- -ing 35 in the regulator casing 8 and is supported therein, a suitable anti-rattling 4spring 39 being mounted between a wall of the opening and the pawl 36.

It will be noted that the pawl 36 has a lost motion connection with the bottom of the lever handle 2| in the opening 38. A coil spring 40 and washer 42 are mounted between the lug `4I of the lever handle and the pressed out ears 43 on the pawl 36. If the pawl dentally engages one of the teeth of the ratchet 34, then as soon as the handle I0 and ratchet 34 are turned, the pawl will ride out of dental engagement with the tooth and the spring 40 will cause the pawl to snap into locking engagement with the ratchet between this and the next tooth.

In operation it will be noted that as shown in the full lines, Fig. 2, the regulator is locked through the pawl 36 and ratchet 34 and the window panel I is locked by the interengagement of the bolt I3 and the keeper opening 21 in the channel III. To release both `the regulator and the window panel the lever handle 30 is swung counterclockwise. as indicated by the arrow to the dotted lin position. This, as described above, retracts the bolt I3 and the lug 4I engages the head 31 of the pawl 36 to retract the other end of the pawl from engagement with the ratchet 34.

If the panel I is swung to any open position and thelever handle 26 swung to the full line position shown in Fig. 2, the pawl 36 will engage the ratchet 34 to lock the regulator and project the bolt I3. However, since the regulator is dogged by the pawl 36, the window panel I can- .not be closed. Therefore this arrangement positively prevents swinging the panel I closed when the bolt I3 is projected which would cause the panel to collide with thebolt and damage either or both.

If the window glass I is slightly open so that the channel frame I2 is oiset from the bolt I3 and the operator throws the lever 30 to the full line position, Fig. 2, to lock the regulator it may be that the pawl 36 will dentally engage one of the teeth of the ratchet 34. However, this will make no di'erence because if a thief now inserts a. looped wire through the opening caused by the slightly opened window glass I to engage the regulator handle II and turn the same the pawl 36 will ride oil the ratchet tooth with which it is dentally engaged into the valley between the two consecutive teeth thus clogging thehandle against further rotation.
